Configure the CData JDBC Driver for Wave Financial in a Connection Pool in Tomcat

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Wave Financial data from a connection pool in Tomcat.

Connect to Wave Financial Data through a Connection Pool in Tomcat

1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
2. Add a definition of the resource to the context. Specify the JDBC URL here.

   Connect using the API Token

   You can connect to Wave Financial by specifying the APIToken You can obtain an API Token using the following steps:

   1. Log in to your Wave account and navigate to "Manage Applications" in the left pane.
   2. Select the application that you would like to create a token for. You may need to create an application first.
   3. Click the "Create token" button to generate an APIToken.

   Connect using OAuth

   If you wish, you can connect using the embedded OAuth credentials. See the Help documentation for more information.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Wave Financial JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.wavefinancial.jar

   Fill in the connection properties and copy the connection string to the clipboard.

   You can see the JDBC URL specified in the resource definition below.

   <Resource name="jdbc/wavefinancial" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.wavefinancial.WaveFinancialDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:wavefinancial:InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />

   To allow a single application to access Wave Financial data, add the code above to the context.xml in the application's META-INF directory.

   For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Wave Financial for all applications.

3. Add a reference to the resource to the web.xml for the application. Wave Financial data JSP jdbc/WaveFinancial javax.sql.DataSource Container
4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/WaveFinancial"); Connection conn = ds.getConnection();
